While I agree with you, at least FFVII had the characters keep growing when they weren't in the party. I've never understood the point of forcing you to go back and re-level characters for whatever reason, especially in games where you're forced to use certain characters at some points. I mean yeah, I never used Aeris, but at least by the time we got to the temple of the ancients she was still servicable. So as long as the party members not being used still grow, I'm good to go with that.
